I know about the very expensive AGM-88E, the posterchild of ARMs that shall not fail so badly as original HARM over Yugoslavia did.<br /><br />Even an anti-radar missile that continues to fly along the direction of the last emissions and uses an imaging sensor and pattern recognition algorithms to pick up the radar target after it ceased to emit is stupid.<br /><br />For one, it would still aim at a good decoy that gets its luneberg lens radiated at by the actual radar. Second, any radar on a mast or with rapid disguise capability (net, folding container etc.) can defeat an AGM-88E. <br />Imagine this https://www.saab.com/products/camosphere with a decoy for imaging sensors nearby.<br /><br />Meanwhile, a drone having a 30x zoom picture of a missile launch location or detected and IDed radar cannot be negated by lowering a mast or using quick disguise.<br /><br />So yes, a missile is stupid. I doubt AGM-88E is worth its USD 1+M price in air/land.S Ohttps://www.blogger.com/profile/03359796414832859686noreply@blogger.comtag:blogger.com,1999:blog-386077914312449748.post-5730877340288232722022-06-17T20:22:04.703+02:002022-06-17T20:22:04.703+02:00@SO: "Anti-radar missiles are stupid; it'...@SO: "Anti-radar missiles are stupid; it's easy to deceive them, such as by radiating towards a Luneburg lens."<br /><br />And you know this true with current missiles how? INS was integrated into USN and USAF missiles like RIM-66/67, SM-2/ER in the late 1960s, including the “stupid” anti-radiation variants (hint: some missiles can track the last emitter location, not just use home on jam and other techniques to destroy their targets). You might want to study the employment of RGM-8H, a surface-to-surface anti-radiation version of the RIM-8 Talos SAM in Vietnam.<br /><br />The current HARM has INS/GPS guidance installed; the following tells you that antiradiation missiles have had a lot going on under the hood for decades:<br /><br />"The AGM-88E Control Section incorporates a GPS aided inertial navigation suite (INS) and a Weapons Impact Assessment (WIA) transmitter. The GPS/INS provides AARGM point-to-point capability and missile avoidance/<br />impact zones.” https://www.af.mil/About-Us/Fact-Sheets/Display/Article/104574/agm-88-harm/<br /><br />GABAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-386077914312449748.post-83978991943038077972022-06-12T10:33:54.972+02:002022-06-12T10:33:54.972+02:00Well, the transceiver needs to be at the antenna a...Well, the transceiver needs to be at the antenna afaik. The processing could be relocated, connected by a fibreoptic cable. The costs problem today is that AESA antennas are so good, and their antenna modules are transceiver and antenna in one.<br /><br />To separate components between different vehicles also reduces mobility very much, it adds a drill for connecting and disconnecting that takes minutes (and is an accident hazard when you also disconnect an electricity generator).<br /><br />Anti-radar missiles are stupid; it's easy to deceive them, such as by radiating towards a Luneburg lens.<br />The bigger problem is what we see in Ukraine; recce assets with imaging seeing the target vehicle, and missile launch smoke trails.S Ohttps://www.blogger.com/profile/03359796414832859686noreply@blogger.comtag:blogger.com,1999:blog-386077914312449748.post-70042640117528200232022-06-12T08:51:41.237+02:002022-06-12T08:51:41.237+02:00Very interesting post.

It seems much more sensible to have the cheapest possible radar antenna, even without processing units, separated from the rest of the system and connected by com link or a cable to the signal processing unit, and this connected the same way to the launcher.<br /><br />That way you can have your radar antenna destroyed and use one or more replacements.<br /><br />Maybe I'm missing something that I don't understand.<br /><br />JMAnonymousnoreply@blogger.com
